Toxicity of crude organic extracts from the zoanthid Palythoa caribaeorum: A biogeography approach

Abstract The effects of thermal compression on the organic-soluble material of a uniform wood substrate, hybrid poplar (clone OP-367), has been studied. Poplar veneers were preconditioned to 0% or 8% moisture content and subsequently hot pressed at 150°C, 200°C, and 250°C. The dichloromethane (DCM) extracts were characterized by various hyphenated analyses [gas chromatography-mass spectrometry (GC-MS), analytical pyrolysis (Py-GC-MS), electrospray ionization-mass spectrometry (ESI-MS), and gel permeation chromatography (GPC)]. The yields and composition of extractable compounds were markedly influenced by treatment at 250°C compared to those obtained at lower temperatures. Most importantly, the organic extracts contained a significant portion of lignin-derived compounds after treatment at 250°C.

Therapeutic Properties

Herein, a comprehensive review is given focusing on the chemical profiles of the essential oils (EOs), non-volatile compounds, ethnobotany, and biological activities of different Haplophyllum (Rutaceae family) species. To gather the relevant data, all the scientific databases, including Scopus, ISI-WOS (Institute of Scientific Information-Web of Science), and PubMed and highly esteemed publishers such as Elsevier, Springer, Taylor and Francis, etc., were systematically retrieved and reviewed. A wide array of valuable groups of natural compounds, e.g., terpenoids, coumarins, alkaloids, lignans, flavonoids, and organic acids have been isolated and subsequently characterized in different organic extracts of a number of Haplophyllum species. In addition, some remarkable antimicrobial, antifungal, anti-inflammatory, anticancer, cytotoxic, antileishmanial, and antialgal effects as well as promising remedial therapeutic properties have been well-documented for some species of the genus Haplophyllum.

Ethylhexyl Phthalate

This study investigated the occurrence of di (2-ethylhexyl) phthalate (DEHP) di-n-butylphthalate (DBP) and bisphenol A (BPA) in river sediment. The samples were collected from three selected points and extracted by sonication, using n-hexane and ethanol. The organic extracts were analyzed by gas chromatography with flame ionization detection (GC/FID). DBP and BPA were not detected. The average concentrations of DEHP range from 0.72 (±0.04) to 27.90 (± 3.05) ng g-1 of sediment. The best solvent for the extractions was n-hexane. However ethanol also shows good extraction yields of DEHP. These results showed an important anthropic contribution for the river contamination by endocrine disruptors.
